[PROBLEM] Auto-update to RC3 -> playing video files not working anymore

[syco]

Hi guys,

I had auto-update activated, because I thought it is a good thing.

Well, when I came home yesterday night, I tried to play a movie
or a series file, but I can hear only the sound. The video output
is not given. Sometimes the screen stays black, sometimes it just
shows the circling thing or the normal Xbian interface with the
movies, series, music menu.

So, I did some restarts and apt-get updates/upgrades, but that
did not help. They do not go through with an error like "root is not
existing volume" or so.

Thanks for your help.
